Subject: Added support for JOIN, QUIT, PART, NICK in the IRC bridge

- It'll now show messages such as:
  [ #irc ] User IRC.<nick> joined the channel.
  [ #irc ] User IRC.<nick> left the channel. [Quit: <quit message>]
  [ #irc ] User IRC.<nick> left the channel. [<leave message>]
  [ #irc ] User IRC.<old nick> is now known as IRC.<new nick>"
- To disable, comment out the respective entries in irc_bot_init.
